Claims (11)

  1. Groupe motopompe centrifuge comprenant un moteur d'entraînement électrique (4) et un dispositif de commande (6) qui possède un convertisseur de fréquence (8) pour la commande de la vitesse de rotation du moteur d'entraînement (4), caractérisé en ce que
    le dispositif de commande (6) est construit de telle sorte que, dans une plage de commande (S3) qui est située dans la plage de faible débit (Q) à haute pression (H) et/ou dans la plage de grand débit (Q) à basse pression (H) et dans laquelle, en cas de réglage traditionnel du moteur, la performance hydraulique est limitée par la vitesse de rotation maximale, un affaiblissement du champ est produit dans le moteur d'entraînement (4) sous l'effet duquel la vitesse de rotation du moteur d'entraînement (4) est augmentée, dans le dispositif de commande (6), est connecté, en amont du convertisseur de fréquence (8), un convertisseur de tension (10, 12) au moyen duquel il est possible de modifier une tension intermédiaire (UVDC) amenée au convertisseur de fréquence et
    le dispositif de commande (6) est construit de telle sorte que, dans une première plage de commande (S1), la tension de sortie du convertisseur de fréquence (8) soit modifiée par modification de la tension intermédiaire (UVDC) tandis que le convertisseur de fréquence (8) travaille avec le facteur d'utilisation des impulsions maximum pour sa tension de sortie.
  2. Groupe motopompe centrifuge selon la revendication 1, caractérisé en ce que le moteur d'entraînement (4) possède un rotor à aimant permanent.
  3. Groupe motopompe centrifuge selon la revendication 1 ou 2, caractérisé en ce que le dispositif de commande (6) est construit de telle sorte que l'affaiblissement du champ soit produit par le fait que l'angle de charge (ρ) du courant par rapport au champ magnétique (2) du rotor est porté au-delà de 90°, de sorte que le courant (I1) et la contre-tension induite (E1) ne soient plus en phase.
  4. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le dispositif de commande (6) est construit de telle sorte que l'affaiblissement du champ soit mis en œuvre de telle sorte que la puissance électrique maximale (ρ) du groupe motopompe centrifuge soit utilisable même dans la plage de faible débit (Q).
  5. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le convertisseur de tension (10, 12) est un convertisseur alternatif-continu (AC-DC) ou un convertisseur continu-continu (DC-DC) à tension de sortie variable (UVDC).
  6. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le convertisseur de tension (10, 12) est un convertisseur élévateur de tension et/ou un convertisseur abaisseur de tension.
  7. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce qu'au moins un condensateur (20) est intercalé entre les pôles de sortie du convertisseur de tension (10, 12).
  8. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le dispositif de commande (6) est construit de telle sorte que, dans une deuxième plage de commande (S2), la tension de sortie du convertisseur de fréquence (8) soit modifiée par réduction du facteur d'utilisation des impulsions du convertisseur de fréquence (8), tandis que la tension intermédiaire (UVCD) est de préférence réglée sur une tension minimale fixe (UVDC_min)ou sur une tension minimale (UVDC_min) qui est dans un rapport prédéterminé par rapport à la tension du réseau (2).
  9. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le dispositif de commande (6) est construit de telle sorte que la première plage de commande (S1) soit une plage de grande puissance du groupe pompe.
  10. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce que le dispositif de commande est construit de telle sorte que la plage de commande (S3) dans laquelle l'affaiblissement de champ est produit soit une troisième plage de commande (S3) dans laquelle la tension intermédiaire (UVDC) est réglée de préférence sur sa valeur maximale (UVDC_max) par le convertisseur de tension (10, 12).
  11. Groupe motopompe centrifuge selon l'une des revendications précédentes, caractérisé en ce qu'il s'agit d'un groupe motopompe de circulation de chauffage, d'un groupe motopompe pour installations de climatisation, d'un groupe motopompe pour applications thermiques solaires ou d'un groupe motopompe haute pression.
